IPC: H01L23/36
Filed: 1994-06-06
Abstract: PURPOSE:To obtain a heat sink for integrated circuit packages, excellent in radiativity. CONSTITUTION:A heat sink 4 consists of a top plate 1 having a square hole 1a formed at its center; square pillars 2; and a bottom plate 3 to be a base plate. These are all made of aluminum. The bottom plate 3 and the pillars 2 are integrally molded, and the top plate 1 is fitted onto the top of some of the pillars 2, positioned at the center, using the hole 1a of the top plate 1. The thus obtained heat sink 4 is placed on the top of an integrated circuit package 5, a heating element, and is bonded using adhesive excellent in thermal conductivity. Heat from the integrated circuit package 5 heats air between the bottom plate 3 and the top plate 1, and the heated air goes up through the through hole 1a at the center of the top plate 1. Further, cool air comes in from the flank between the bottom plate 3 and the top plate 1 to form spontaneous convection of heat. This spontaneous convection accelerates the heat radiation by the heat sink 4.

Title: Carrying speed detector
Inventor: YAMAGUCHI TADASHI
IPC: G01P3/54
Filed: 1985-06-07
Abstract: PURPOSE:To extend the speed detection range by arranging plural sped sensors along a carrying path and selecting speed sensors alternatively in accordance with advance of a carrying body. CONSTITUTION:While a position sensor 102-2 detects a pallet 1, a low-level signal is supplied to the first input terminal of an AND gate 112-1 in an important position G3 by an inverter 13-2. The pulse signal of an optical switch 82-2 and that of an optical switch 82-1 are inputted to a converter 9 without superposing each other thereby even if the length between sensors 102-2 and 103-1 is shorter than the overall length of the pallet 1 because the length between important positions G2 and G3 is shrot. Thus pulse signals outputted in speed detection ranges adjacent to each other are not supplied simultaneously to the converter 9 even if these ranges overlap because the interval between important positions is short. Consequently, the speed detection range is extended to control the speed finely in wide ranges of important positions of the carrying path.
